Flow velocity is directly proportional, and with axisymmetric flow regime（Laminar flow or turbulent flow）It is unrelated.Electromagnetic flowmeter is without machinery inertial, reaction spirit
It is quick, instantaneous pulsating flow, and good linearity can be measured, therefore measuring signal can be directly converted into converter is linear
Standard signal exports.
But with the development of the society, the arrival in industrial 4.0 epoch, intelligence is the development trend of various industrial equipments,
Traditional electromagnetic flowmeter has a single function, and often only has the function of that metering, when reading need that scene is gone to carry out meter reading one by one,
Under the working environment for having multiple flowmeters, taking time and effort particularly；Electromagnetic flowmeter is the speed by measuring conducting liquid simultaneously
Degree determines the volume flow under working condition, should measure mass flow for liquid medium according to measuring requirement, measure medium
Flow should be related to the density of fluid, and different fluid medium has different density, and varies with temperature, if Electromagnetic Flow
Meter converter does not consider fluid density, and it is often inaccuracy only to provide the measurement result that the volume flow under normal temperature state obtains
, another disadvantage of electromagnetic flowmeter is also easy to produce non-full pipe phenomenon, causes to count in the case where measuring flow rate of liquid reduction
Measure the mistake of data.
